In respect to this, what makes up the cell membrane?
Phospholipids make up the basic structure of a cell membrane. This arrangement of phospholipid molecules makes up the lipid bilayer. The phospholipids of a cell membrane are arranged in a double layer called the lipid bilayer. The hydrophilic phosphate heads are always arranged so that they are near water.
Likewise, what is the cell wall made of? Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.
Herein, what makes the cell membrane fluid?
Cell membrane is fluid because individual phospholipid molecules and proteins can diffuse within their monolayer and thus move around. The fluidity is affected by: The length of the fatty acid chain. Here, the shorter the chain the more fluid is the membrane.
Do all cells have DNA?
Nearly every cell in a person's body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
